Three long frictionless rods are fixed parallel to each other in a horizontal plane with separation d between adjacent rods. The rods wear identical sleeves A, B, C and D each of mass m and charge q. Initially the sleeves B, C and D are arranged in a line perpendicular to the rods and the sleeve A is far away from them as shown in the figure. In this way, the sleeves B, C and D are in a state of unstable equilibrium and have no electrostatic interaction with the sleeve A. If the sleeve A is launched towards the right with an initial velocity u, find velocities of all the sleeves when they acquire steady motion. Consider all possible cases.
